Pro MX Configuration Checker & Advanced Security Audit

MX Records Tools

Audit your entire email ecosystem for modern security standards. Validate MTA-STS enforcement, check TLS-RPT monitoring, audit BIMI readiness, and guarantee encrypted TLS deliverability.

Ready to Audit Security

Enter a domain to perform a deep configuration and security check. We will validate your MX, SPF, DMARC, MTA-STS, TLS-RPT, and BIMI records instantly.

Why Use MX Configuration Checker?

Go beyond basic MX lookup. Audit your entire email ecosystem for modern security standards to guarantee deliverability, protect your brand, and stop spoofing.

SPF & DMARC Validation

Instantly checks your domain for valid Sender Policy Framework (SPF) and DMARC configurations to ensure authorized senders and prevent phishing attacks.

MTA-STS Enforcement

Detects the presence of Mail Transfer Agent Strict Transport Security (MTA-STS) to verify that your domain enforces encrypted TLS connections for all inbound mail.

TLS-RPT Monitoring

Checks if SMTP TLS Reporting (TLS-RPT) is configured. This crucial protocol ensures you receive reports when external servers fail to deliver encrypted emails to you.

BIMI Brand Indicators

Audits your domain for BIMI readiness. A valid BIMI record allows supported email clients (like Gmail and Yahoo) to display your official, verified brand logo next to your emails.

RFC Compliance Check

Our robust backend analyzer detects fatal RFC misconfigurations, such as pointing an MX record to a direct IP, local addresses, or invalid Null MX implementations.

This deep configuration logic utilizes a robust C# backend API to fetch and analyze multiple complex DNS records concurrently, guaranteeing high-speed and accurate results.
